Objective: Programmed cell death-1 (PD-1, encoded by PDCD1) regulatory network participates in glioblastoma multiforme development. However, such a network in trastuzumab-resistant human epidermal growth factor receptor 2-positive (HER2+) breast cancer remains to be determined. Accordingly, this study was aimed to explore the PD-1 regulatory network responsible for the resistance of breast cancer cells to trastuzumab through a bioinformatics approach.

Background: HER2-targeted antibody-drug conjugates (ADCs) have revolutionized the treatment landscape of metastatic breast cancer. However, the efficacy of these therapies may be compromised by genomic alterations. Hence, this study aims to identify factors predicting sensitivity to HER2 ADC in metastatic breast cancer.

Article Synopsis
- The study investigates the role of ERBB3 expression in HER2-positive breast cancer and its potential impact on treatment resistance.
- Through various bioinformatics techniques and machine learning algorithms, the researchers identified three key genes—PBX1, IGHM, and CXCL13—that are linked to ERBB3 expression and can serve as prognostic markers.
- Findings suggest that these genes may influence breast cancer cell behavior and prognosis, emphasizing their significance in understanding HER2-positive breast cancer treatment outcomes.
Dehydroevodiamine Alleviates Doxorubicin-Induced Cardiomyocyte Injury by Regulating Neuregulin-1/ErbB Signaling.

Doxorubicin (DOX) is a widely used antitumor drug; however, its use is limited by the risk of serious cardiotoxicity. Dehydroevodiamine (DHE) is a quinazoline alkaloid which has antiarrhythmic effects. The aim of this study was to investigate the protective effect of DHE on doxorubicin-induced cardiotoxicity (DIC) and its potential mechanism.
